Microstructural Characterization of PM 625-Type Materials

Crucible has been a pioneer in manufacturing PM 625-type materials for applications where good corrosion resistance and medium to high strength characteristics are a necessity. A unique feature of the PM version of these type of materials is the ability to control strengthening by conventional heat treatment cycles. There are some microstructural responses in the alloy which help explain the properties. A microstructural study of the powder before and after consolidation sheds some light on what is happening during the processing of these alloys.
